When you want a to make a drive available on the network, Samba is a good solution that works with most other operating systems.
sudo apt-get update sudo apt-get install samba smbclient
Check if the service is running with
sudo systemctl status smbd
Update firewall to allow Samba connections
sudo ufw allow 'Samba'
It's possible to configure the shares via finder. Right click on the folder / drive and go to either "Properties -> Sharing tab" or "Local Network Share"
Allowing "Guest" will not require a password. Anyone on the local network can connect to the share.
If you want to use a standard user account to connect to them, you'll need to assign a samba password to the account:
sudo smbpasswd -a account
sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.orig sudo cp ~/previous/system/smb.conf /etc/samba/smb.conf sudo /etc/init.d/samba reload
sudo mount -t cifs //192.168.1.234/data ~/shared-drive
